Site map maybe one solution but its not the solution I look for. What makes you lot think a site map would help get more pages spidered when I bet you haven’t even looked at his site? Surely if it’s the navigation that is the problem being too deep then a better solution is to change the navigation or include a breadcrumbs tray.
BUT let actually have a look at his site....
The pages are all linked using shallow structure so a site map would do nothing for the site :/
I am not sure about this but is it fair to say the more inbound links you get the higher the
PR and the higher the
PR the more WebPages are spidered? No one can see there
PR at the moment but you have over 10 inbound links and your
PR is higher than indicated on the tool bar because Google has not updated the toolbar in ages. I would have a wild guess your
PR is 5 and to get that many pages indexes you need to be in the magic 6 zone.
Your solutions: your sbd.bcentral.com is a good listing and should help! Forum links like this don’t do much as I have experimented with them but just keep those links coming. If you actually sell a product then its best to look at other forms of revenue like pay per click and offline ads.
